Geothermal energy

Geothermal energy comes from heat stored underground. It can provide both steady, reliable power generation and abundant direct heat for multiple uses.

Geothermal power generation works by using the high-temperature heat under the earth’s surface to produce steam, which then drives turbines to generate electricity. This key renewable source provides over one-fifth of electricity in El Salvador, Kenya and the Philippines. More than 90% of homes in Iceland rely on direct geothermal heat. To promote wider geothermal energy development, IRENA has co-ordinated the formation of the Global Geothermal Alliance (GGA) – a platform for enhanced dialogue and knowledge sharing for coordinated action to increase the share of installed geothermal electricity and heat generation worldwide.
